Adjustable Voltage Output Multifunction 2A High Speed LDO Regulator
XC6230 Series
Based on a CMOS process, the XC6230 series are high-speed LDO regulators with a maximum output current of 2A.
A Pch driver Tr with a low ON resistance of 0.17Ω is incorporated in the IC, and stable output can be obtained even
when the dropout voltage is small, making this product ideal for a battery voltage or the end stage of a DC/DC converter.
Rush current protection, reverse current protection, and thermal shutdown protection circuits are incorporated as
protective functions, and the IC is housed in the USP-6C package to enable space-saving mounting as a protective
function IC. Also, an adjustable output voltage function enables any voltage to be set within the range 1.2V to 5.0V, and
an adjustable current limiting function enables any current to be set within the range 0.3A to 2.5A.

Operating Ambient Temperature
Inrush Current ProtectionWhen the IC starts, this function limits the current that suddenly flows from the input pin (VIN) to the output pin (VOUT) to charge the output stabilization capacitor (CL). When CL=4.7μF, the rush current is limited to 500mA or less, making it possible to design a safer circuit.
When the output voltage is higher than the input voltage, the reverse current protection function prevents current that flows in reverse from the output pin (VOUT) to the input pin (VIN).
Reverse Current Protection
A thermal shutdown (TSD) circuit is incorporated to protect the IC from overheating. When the junction temperature reaches the detection temperature (150℃), this function forcibly shuts the driver transistor OFF.
